Select frontend network callbacks for auto_sockets=android instead of opening a denied netlink monitor. Preserve monitor descriptor ownership, keep native monitoring failures fatal, and release caller config on failed Android core creation and restart.
Register ConnectivityManager before requesting startup, report readiness after SERVICE_STARTED, and refresh addresses after initialization with serialized updates and generation checks. Add regression coverage for denied netlink, socket failures, address updates, and fd=0 preservation. Record the separate cancellation issue for startup before readiness.
Validation: full check.sh passed, including proxy/burst/load integrations. Clean Android build installed successfully on SM-A525F and Q8; logcat confirms both cores initialized and entered the poll loop with external monitoring and post-start address refresh.
Receive keepalive through the owning ETCP link, preserve RX deadlines, and report routing metrics without TUN. Use independent netlink requests and track installed routes for rollback. Reject incomplete resource initialization and release partially constructed cores while preserving caller config ownership.
Validated startup failure and rollback, padded keepalive, standby, STCP traffic, transport lifecycle, dynamic sockets, and daemon startup. Real TUN/netlink checks passed in an isolated Linux network namespace; modified modules passed FreeBSD compilation checks.
